BACKGROUND OF THE INVENTION

This invention relates generally to the field of mechanical devices forpolishing purposes and more specifically to a machine for polishingsubmerged surfaces, i.e. a pool.

Polishing procedures are based on friction of abrasive material betweenthe polished surface and an auxiliary surface that can be the supportivemedia for the abrasive materials. The abrasive material is always harderthan the surface to be polished and the auxiliary surface must beresistant to the abrasive material. As a general rule, the size of thegrain of the abrasive material would dictate the polishing effect.

At first the process was a manual one involving a hand tool to apply thepolishing material against the surface to be polished. Later on theabrasive material was glued to a hard surface creating in this way apolishing tool that required no abrasive material to operate. Thelimitation was that in time the tool would be worn out of the glued orfixed abrasive material reducing first the efficiency and then theutility of the same.

A new improvement was to fix the abrasive material to flexible surfacessuch as paper or cloth allowing it to be used on its own or attached toa tool. In this way the tool becomes reusable with new abrasiveattachments.

The next step was to design and produce hand tools powered by anexternal source, mainly electrical power but also pneumaticallyoperated.

The invention introduces the hydraulic power to operate these polishingdevices.

Rotating abrasive polishing tools are widely used in the industry butsome limitations apply to their use on submerged surfaces. The first andmost important is the nature of the power for the tool. Electric powermakes it unsafe to operate under water, specially salt water. Pneumaticpower can be used but introduces the problem of bubbles which cannot beavoided and must be diverted.

The limitations in the present technology specially for submergedsurfaces can be overcomed by this invention.

BRIEF SUMMARY OF THE INVENTION

The primary object of the invention is that it is a hand held device.

Another object of the invention is to use hydraulic power.

Another object of the invention is that it operates both submerged andnon submerged.

Another object of the invention is that is powered by pressurized water,i.e. by a pressure cleaning pump.

A further object of the invention is to allow exchangeable polishingdisks.

Yet another object of the invention is that it does not overload thepressure pump.

Other objects and advantages of the present invention will becomeapparent from the following descriptions, taken in connection with theaccompanying drawings, wherein, by way of illustration and example, anembodiment of the present invention is disclosed.

In accordance with a preferred embodiment of the invention, there isdisclosed a machine for polishing submerged surfaces, i.e. a poolcomprising: hydraulic power, only one rotating element, a two partcasing, a pressure connector, and standard commercial polishing disks.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Detailed descriptions of the preferred embodiment are provided herein.It is to be understood, however, that the present invention may beembodied in various forms. Therefore, specific details disclosed hereinare not to be interpreted as limiting, but rather as a basis for theclaims and as a representative basis for teaching one skilled in the artto employ the present invention in virtually any appropriately detailedsystem, structure or manner.

A machine comprising a two part casing enclosing a low speed hydraulicturbine fixed to the only rotating axle. This axle rotates by means ofthe motion generated by the turbine while receiving the pressurizedwater injected through the pressure connector. Attached to thetermination of the axle is a fixed disk that allows the attachment ofthe abrasive material disks.

The incoming pressurized water forces the turbine to rotate with theaxle generating the rotary motion of the disk. The water is thendischarged at low pressure towards the rotating disk.

The abrasive disks can be changed in accordance to the surface andpolishing needs and standard commercial abrasive elements can be used.The machine can be used on submerged surfaces i. e. a pool.

While the invention has been described in connection with a preferredembodiment, it is not intended to limit the scope of the invention tothe particular form set forth, but on the contrary, it is intended tocover such alternatives, modifications, and equivalents as may beincluded within the spirit and scope of the invention as defined by theappended claims.

1. A machine for polishing submerged surfaces, i.e. a pool comprising:Consumes hydraulic power Only one rotating element; Two part casing;Pressure connector; and Standard commercial polishing disks.
